Lake Hulun on the Hulun Buir Plain, China

Lake Hulun is a large lake in the Hulun Buir Plain, northern part of the Inner Mongolia Autonomous Region, northern China, near the border with Mongolia.

The lake, which appears light green in this image, is fed by two rivers that rise in Mongolia: the Kerulen (Kelulun), which flows from the west, and the Orxon (Orshun), which flows from the south. The surface area of Lake Hulun has fluctuated considerably based on variations in the climate.
